Driving Pattern

• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.

  Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the shortest.

  Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed within zone A.

  *: Normal conditions refer to the following:

• Sea level
• Flat road
• Ambient air temperature: 20 - 30°C (68 - 86°F)
• Diagnosis is performed as quickly as possible under normal conditions.

  Under different conditions [For example: ambient air temperature other than 20 - 30°C (68 - 86°F)], diagnosis may also be performed.

Pattern 1:

• The engine is started at the engine coolant temperature of -10 to 35°C (14 to 95°F) 

  (where the voltage between the ECM terminal 46 and ground is 3.0 - 4.3V).

• The engine must be operated until the engine coolant temperature is greater than 70°C (158°F) 

  (where the voltage between the ECM terminal 46 and ground is lower than 1.4V).

• The engine is started at the fuel tank temperature of warmer than 0°C (32°F) (where the voltage between the ECM terminal 95 and ground is less than 4.1V). 

Pattern 2:

• When steady-state driving is performed again even after it is interrupted, each diagnosis can be conducted. In this case, the time required for diagnosis may be extended.

Pattern 3:

• Operate vehicle following the driving pattern shown in the figure.
• Release the accelerator pedal during decelerating vehicle speed from 100 km/h (62 MPH) to 0 km/h (0 MPH).

Pattern 4:

• The accelerator pedal must be held very steady during steadystate driving.
• If the accelerator pedal is moved, the test must be conducted all over again.

Pattern 5:

• Activate "INSPECTION MODE 1" ( MODE 1 ) to start engine, and wait at least 2 hours. Then turn ignition switch OFF and wait at least 90 minutes.

*1: Depress the accelerator pedal until vehicle speed is 100 km/h (62 MPH), then release the accelerator pedal and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 100 km/h (62 MPH) again.

*2: Checking the vehicle speed with GST is advised.
